Starting a Business in Hong Kong: Tax Basics

Congratulations on starting your Hong Kong business! Understanding your tax obligations from day one helps you stay compliant and avoid penalties. This guide covers everything you need to know about first-year business tax.

Timeline of First Year Tax Events

Month 1: Business Registration

Within 1 month of starting business:

  • Register for Business Registration Certificate
  • Fee: HK$250 (annual levy waived for 2024/25)
  • Obtain Business Registration Certificate

Month 1-18: First Accounting Period

Your first accounting period runs from:

  • Start date: Date of incorporation or business commencement
  • End date: Your chosen year-end date

Important: First period can be up to 18 months.

Month 18-24: First Tax Return

Approximately 18 months after incorporation:

  • IRD issues first Profits Tax Return
  • Usually issued in April of the second year
  • Filing deadline: 1-3 months from issue date

First Profits Tax Return

What to Expect

Your first tax return will cover:

  • Period from incorporation to first year-end
  • May be shorter or longer than 12 months
  • Requires audited accounts (for corporations)

Key Sections

  1. Business particulars: Nature of business, accounting period
  2. Financial information: Revenue, expenses, profit/loss
  3. Tax computation: Calculation of assessable profits
  4. Offshore claim: If applicable

First Year Deductions

Startup Costs

Pre-trading expenses may be deductible if:

  • They would be deductible if business was operating
  • Incurred within reasonable time before commencement
  • Related to the business

Examples of deductible startup costs:

  • Professional fees for incorporation
  • Initial marketing and advertising
  • Website development
  • Business registration fees
  • Staff recruitment costs

Capital Allowances

Significant benefit in first year:

Initial Allowance: 60% of qualifying assets

Example: Purchase computer equipment for HK$100,000

  • Initial allowance: HK$60,000 (Year 1)
  • Annual allowance: HK$30,000 (Year 1)
  • Total Year 1 deduction: HK$90,000

This significantly reduces first-year tax.

Provisional Tax

What is Provisional Tax?

Provisional tax is an advance payment based on your assessable profits. However, there is no provisional tax in your first year.

When It Starts

Provisional tax begins in your second year of assessment:

  • Based on your first year's assessable profits
  • Payable in two installments
  • Can apply for holdover if profits expected to decrease

Common First Year Scenarios

Scenario 1: Company Makes a Loss

Situation: First year loss of HK$200,000

Tax implications:

  • No profits tax payable
  • Loss can be carried forward indefinitely
  • Offset against future profits

Action: Still must file tax return showing the loss

Scenario 2: Small Profit

Situation: First year profit of HK$500,000 (corporation)

Tax calculation:

  • HK$500,000 x 8.25% = HK$41,250
  • Benefits from two-tiered rate

Action: File return, pay tax by due date

Scenario 3: Short First Period

Situation: Incorporated in November, year-end December (2 months)

Tax implications:

  • Only 2 months of operations
  • Still get full HK$2M at lower rate (not pro-rated)
  • Next period will be 12 months
